Gear drops to neutral when shifting down

Hi,
There's seems to be a strange problem (or is it an option?) where when I press both gears levers the gear drops straight to N. This happens to me accidently when I shift down. Is there an option to cancel this??? using G25.
Thanks,
Itay

well... you don't let go... and inforce me to reveal my bad habbit for many years now...
For some strange reason I tend to upshift and then rapidly downshift particularly before hard breaking... don't ask me why... bad habbit.... so what oftne happens is that this very rapid up and down ends out as hitting both levers at the same time...
Anyway - found the parameter on the controller plr file and I disabled it...
Thanks!
Itay
